Signal

Deep navy canvas with bone paper and a single muted-gold accent; institutional with quiet weight.

A single self-contained HTML deck — typography, palette, decorative system, and slide vocabulary are all tuned together. Mixing layouts across templates breaks the system; stay inside this one.

Scheme: mixed
Formality: high
Density: high
Slides in demo: 18

Best for

Anything that should feel weighty, considered, and credibly institutional: investor decks, board presentations, consulting deliverables, legal / policy briefs, advisory pitches. Also a strong choice for tech, research, or brand work that wants to read as quietly authoritative rather than loud.

Avoid for

Contexts that should feel hot, fast, or intentionally playful — the navy + gold restraint commits to a sober voice.

Workflow

Clone example.html into the user's workspace as the working file.
Replace placeholder content with the user's real headlines, body copy, numbers, names, dates, and section labels. Match existing dimensions when swapping image placeholders.
Preserve the design system. Never substitute fonts, recolor the palette, restructure the layout grid, or strip decorative elements (corner brackets, paper grain, geometric shapes, illustrated SVGs). They are part of the identity.
Adjust deck length by duplicating layouts. If the user has more content than the demo holds, duplicate an existing slide of the most appropriate layout. If less, drop slides from the bottom. Update page-number labels.
Designing missing layouts: if a slide needs a layout the template doesn't have, design it from scratch using the same fonts, palette, decorative vocabulary, spacing rhythm, and component grammar — never bail to a different template.
Keep the navigation runtime as shipped. If the deck ships an assets/deck-stage.js or inline keyboard handler, leave it intact.
